Quick Start List for Platform
2-5 Operation
Power Up
17) Ensure that EVM potentiometers VOLUME, BUFFGAIN, and BB ATT are
set to their approximate mid points.
18) Verify correct voltage and input polarity and set the external power supply
to ON. If V
CC
and an onboard regulator EVM are used to provide V
DD
, set
platform power switch S1 to ON.
Platform LED2 should light indicating the presence of V
DD
, and the evaluation
modules installed on the platform should begin operation.
19) Adjust the signal source level as needed.
Evaluation module controls
20) The EVM VOLUME potentiometer controls the volume of the
platform
OUT+/– outputs. Turn this control clockwise to increase the volume.
21) The EVM BUFFGAIN potentiometer controls the volume to both the
platform OUT+/– outputs and the EVM LDOCK/RDOCK output
terminals. Turn this control clockwise to increase the volume.
22) The EVM BB ATT potentiometer controls the attenuation of the bass
boost. Turn this control clockwise to decrease the bass boost attenuation.
23) The EVM ACTIVE and PASSIVE potentiometers control the cutoff
frequency for their respective filters. Turn these controls clockwise to
increase the filter cutoff frequency.
